SHEARS.

SPECIFICATION forming part of Letters Patent No.` 477,343, dated June21, 1892.

Application iilcd December 29, 1891.

To all whom it mayiconacrn:

Be it known thatvI, EDWARD F. VEBER, a subject of the Emperor ofGermany, residing at Reading, in the county of Berks, State ot'Pennsylvania, have invented certain I mprovements in Scissors or Shears,of which the following is a specification.

My invention relates to that class of scissors or shears in which theblades are held together by a spring so as to maintain proper contact ofthe cutting-edges.

My main objects are, first, to enable the blades to be taken apart withthe greatest driver or any tool whatever, and, second, to enable thetension of the spring to be readily varied without employing an ad jListing-screw. These objects I attain by means of a very simple andinexpensive construction, the essential features of which will be fullyexplained in connection with the accompanying drawings.

Figure 1 is a plan view of a pair of scissors having my inventionadapted thereto, the blades being represented as closed. Fig. 2 isapartial edge view of the same on an enlarged scale. Fig. 3 is a viewsimilar to Fig. 1, butf' shows theblades opened and indicates theinanner of removing or placing in position the spring-plate. Figs. 4 and5 show the springplate and pivot-pin in detail.

The blades A and A', of any ordinary construction,are provided withholes for the passage of the pivot-pin B, by which they ai'e connected.The pin is represented as formed with a head b and a body of uniformdiameter which lits loosely in the pivot-holes, but the projectingportion of which beyond the pivot-blades is grooved on opposite sides,as shown at b b. The means by which this pin is held in place and theblades are maintained in proper contact, whether opened or closed,consists merely of a spring-plate C, of sheet Fig. 4, with a forked endc', a narrower opposite end c, and an intermediate lug or projection c2from the convex surface. The pivot B being in position, the forked endof this spring-plate is entered in the grooves or recesses b b in themannerindicated in Fig. 3 and the end c is pushed sidewise, with aslight strain upon the spring, into engagement with one of a series ofnotches or kerfs d, formed in the outer face of one (or both) of theblades at different distances from the Serial No. 416,451. (No model.)

pivot. The connection of the blades is then complete,the outer face ofthe spring serving to hold the head b of the pivot-pin firmly againstthe blade A by pressing against the portion of the projecting pin whichoverliangs the grooves b b', while its ends c and c bear upon the bladeA', thus holding the two blades in contact.

If it is desired that the spring-pressure be increased or diminished, itis only necessary to push or pull upon the lug c2, so as to move the endc of the spring-plate forward or backward into a different notch orrecess a. The blades, though thus securely held together, may be takenapart in a moment for cleaning, oiling, or sharpening Without the use ofa screw-driver or other tool. These advantages over prior devicesinvolving the use of springs to maintain the blades in contaet, as wellas the superior economy and simplicity 0f my construction, will bereadily understood.

I do not desire to limit myself to the exact construction hereindescribed and shown; but

What I claim is- 1. The combination, with the scissor-blades, of aheaded pivot-pin passing through said blades, and the forkedspring-plate C, engaging, intermediately, the projecting portion of thepin and having its opposite ends bearing upon one of the blades, saidspring-plate being independently removable, substantially in the mannerVand for the purpose set forth.

2. The combination, with the scissor-blades, of a headed pivot-pinpassing through said blades, and a spring-plate having a forked endengaging the projecting portion of said pin and its opposite endadaptedto engagea series of notchesain the plate upon which 1t bears,substantially as and for the purpose set forth. Y

3. The coinbination,-with the scissor-blades provided witha series ofnotches a and a pivot-pin connecting the same, of the forkedspring-plate having one end adapted to engage said notches and aprojection c2 thereon whereby to adjust the same, substantially as setforth.

In testimony whereof I aliix mysignature in presence of two witnesses.

EDWARD F. WEBER.
